Hello again everyone.

I really need serious help here ..

It is still the graphics card problem, and that it is only running under half the speed of that, on the X48..

It is a 9800GX2 card and it is running with two GPUer (as SLI) multi gpu..

In GPU-Z it shows to cards and that SLI is enable, it shows PCIe 2.0 x 16 on both cards, so everything is ok here.

But when I check the hardware in SiSoftware Sandra, there is one card in SLI and one beside that. when I benchmarks in Sandra,for comparison with a similar card, it can only run less than half the speed?? ..

It is as if there is something there are blocking over a certain speed, even if I OC the graphics card, is dont do the slightest difference.

It can run at a certain speed and then it will just not anymore.

I've never had problems on X48.....

Could it be PCIe port there is something with, it must be a hardwre problem, I tried to reinstall the OS and drivers several times ...
